The Altair Lightwave TM Premium Long Eye Relief eyepiece has a very flat, well corrected and wide 68° apparent field of view. The 18mm focal length will provide expansive views of the Moon, planets and deep sky objects. The 20mm Long Eye Relief means you can position your eye 20mm from the eyepiece lens, making this is a very comfortable eyepiece for beginners and experienced observers alike, whether or not you're wearing glasses. An 8-element computer optimized design makes the most of the fully multi-coated optics to provide exceptional contrast and clarity across a wide visual field. Threaded for use with standard 1.25" eyepiece filters.
